Automotive, 125°C Operation, 36 V Input, 40 mA Voltage Regulator with Input Monitoring Reset Function S-19310/5/6 Series Reduces standby current

The S-19315 Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with the reset function, which has high-withstand voltage and low current consumption.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared for the reset function, so the output is stable even if the SENSE pin falls to 0 V. The output form is Nch open-drain output.
